For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Behavior Change |
Description |
---|---|
Deprecation of snmp-server enable traps license global configuration command |
The command was deprecated. The associated MIB, CISCO-LICENSE-MGMT-MIB, is also no longer supported. In place of the deprecated command and unsupported MIB, use CISCO-SMART-LIC-MIB. |
New flag for the IPv6 SGACL monitor mode |
A new flag has been introduced for the IPv6 SGACL monitor mode. This was introduced to address hardware limitation of a single counter shared for IPv4 and IPv6 traffic. The HW_Monitor counter gets incremented irrespective of the type of traffic, which in turn updates the monitor mode flag. With a separate flag for IPv6 and IPv4 SGACL monitor mode, only the corresponding protocol flag is updated depending on the type of traffic. |
show power and show power detail command output |
The show power and show power detail command outputs are modified to display the correct power information of the standby switch. |
